Cleansers, charging and cost: three facial cleansing devices
Last checked 2026-09-25.
Per FOREO's manuals, both LUNA 4 models should not be used with clay-based, silicone-based or grainy cleansers, need no replacement brush heads, and should not be used while charging. PMD's page for the Clean Pro RQ states none of these, so for it they are unknown rather than assumed; its price is $143.99 against $99.00 and $168.99 for the two LUNA models on 2026-09-25.

With no replacement heads documented for either LUNA, owning one costs its price; for the PMD, whether its head needs replacing is not stated. PMD's 20-year warranty covers manufacturer defects and excludes drops and incorrect voltage; a longer warranty is not evidence that a device lasts longer or cleans better.
Kinds of claim on this page: app functions, charging, water, cleanser rules and warranty are manufacturer claims, from the manual or maker page linked in each column (read 2026-09-24); prices and sellers are from the Amazon US listings on 2026-09-25. A cell no source settles says unknown (not stated). There is no product evidence about skin results here: nothing was measured or tested.
Head to head: FOREO LUNA 4 vs LUNA 4 go. What needs the app: using a LUNA 4 without the app.
